Low compression passenger side only

[70gmc]

While doing a compression test on my 350 the driver side was at 1: 140...3: 100...5:120...7:115 and the passenger side was at
2:120...4: 55...6: 40...8:...80 and while its cranking it sprays alot of gas out of the spark plug holes...just looking for any suggestion as to why its like this thank you

Need more info. Carbureted, or EFI? I have to assume it's a carb. You are going to have unburnt fuel, but you should not have "a bunch" unless you have a float issue.

So, you are looking for the causes of low compression? Before I go down that long list, you need to tell us why you were doing a compression test, and how it was running prior to the test. Did you do ANYTHING prior to the test, like adjust valves, etc?
